EL7530 pdf datasheet (Monolith

The EL7530 is a synchronous, integrated FET 600mA stepdown
regulator with internal compensation. It operates with an
input voltage range from 2.5V to 5.5V, which accommodates
supplies of 3.3V, 5V, or a Li-Ion battery source. The output can
be externally set from 0.8V to VIN with a resistive divider.
The EL7530 features automatic PFM/PWM mode control, or
PWM mode only. The PWM frequency is typically 1.4MHz
and can be synchronized up to 12MHz. The typical no load
quiescent current is only 120μA. Additional features include
a Power-Good output, <1μA shut-down current, short-circuit
protection, and over-temperature protection.
The EL7530 is available in the 10 Ld MSOP package,
making the entire converter occupy less than 0.18n2 of PCB
area with components on one side only. The 10 Ld MSOP
package is specified for operation over the full -40°C to
+85°C temperature range.
